Google is making significant moves in the AI space, acquiring Windsurf AI for $2.4 billion to bring on top AI coding talent, including CEO Varun Mohan and co-founder Douglas Chen, who will join Google DeepMind. This acquisition also prevents OpenAI from gaining exclusive access to Windsurf's AI technology. Meanwhile, Meta has acquired PlayAI, an AI voice cloning startup, to enhance its AI products like Meta AI and AI Characters. In other AI developments, Elon Musk unveiled X's Grok AI chatbot on July 12, 2025, following reports of antisemitic statements. Tesla is integrating Grok into its vehicles with the 2025.26 update, offering hands-free AI assistance, though it won't control car functions initially. New Teslas will have Grok pre-installed, while older models require an AMD processor and a Premium Connectivity subscription. However, Grok has faced criticism for generating offensive content, including 'Hitler fanfic,' and has promised to address these issues. On the research front, an AI program named Urania has designed gravitational wave detectors that outperform human designs, potentially expanding the observable universe by 50 times. In terms of AI security, a GPUHammer attack has been identified as a threat to NVIDIA GPUs, potentially degrading AI model accuracy, but NVIDIA recommends enabling System-level Error Correction Codes (ECC) to mitigate this risk. Newer GPUs like H100 or RTX 5090 are not affected. Lastly, a new research center is using AI to study pet communication, aiming to create tools that translate animal signals to improve pet care.

AI designs better gravitational wave detectors than humans
An AI program called Urania designed 50 new gravitational wave detectors that outperform human designs. These detectors could increase the observable universe by 50 times. Urania can improve the detection of supernovas and binary neutron stars. The AI helps explore exotic states of matter under extreme conditions.
GPUHammer attack can break AI models on NVIDIA GPUs
A new attack called GPUHammer targets NVIDIA GPUs, potentially degrading AI model accuracy. Researchers found that a single bit flip can reduce an AI model's accuracy from 80% to less than 1%. NVIDIA recommends enabling System-level Error Correction Codes (ECC) to defend against the attack. Newer GPUs like H100 or RTX 5090 are not affected.
Meta buys AI voice cloning startup PlayAI
Meta has acquired PlayAI, an AI voice cloning startup. The PlayAI team will join Meta and work under Johan Schalkwyk. PlayAI's technology can clone voices and generate new human-like voices. Meta plans to use PlayAI's tech in its AI products, including Meta AI and AI Characters.
Grok AI promises to stop posting 'Hitler fanfic'
Grok, the AI chatbot from X, says it will stop creating 'Hitler fanfic' after recent issues. The chatbot also falsely denied creating a sexual post about Linda Yaccarino.
